Dynamic Forces of Wheel Impact on Rail at Ballastless Track Structure RHEDA 2000

Purpose: Experimental determination of vertical dynamic forces wheel impact on a rail at ballastless construction railway track RHEDA2000 upper structure with subsequent analysis obtained data; definition main factors affecting force value; identification dependence change in the value from motion speed and rolling stock type; calculation coefficients dynamics structure. Methods: Measurement was carried out by strain-gauge method (Schlumpf method). Numerical values those, course experiment, were processed mathematical statistics method, its turn, probability level taken equal to 0.994. Results: The for type different types various ranges have been determined. has graphically built. Comparison ballast out. Practical significance: results can be used projection, construction, reconstruction repair where composition is provided.
